摘要/Abstract

摘要： 采用旋转搅拌装置和 GC-MS 法研究了 pH 值对钙离子存在下树脂沉积的影响．发现 pH 值的降低会导致树脂的沉积pH7∙0是转折点．将这些树脂分离成结合树脂和游离树脂后进行 GC-MS 分析结果表明钙皂和游离树脂对沉积物的形成有共同的贡献结合树脂在低 pH 值和高温下转变为游离树脂．酸性组分对钙皂的形成起重要作用而脂肪酸皂在低 pH 值下更稳定．

关键词: pH 值, 树脂沉积, 钙皂

Abstract: The effects of pH value on resin deposition with the presence of Ca 2＋ were studied by using the device of “Rotating-mixer” and the method of GC-MS analysis．It is found that the decrease of pH value results in resin deposition and pH7∙0is the turning point．The deposits were analyzed by GC-MS after being separated into combined resins and free resins．Experimental results show that calcium soaps and free resins contribute together to deposits formation．The combined resins would change into free resins at low pH and high temperature．Acidic components play an important role in soaps formation and the soaps of fatty acids are more stable at low pH value．

Key words: pH value, resin deposition, calcium soap
